Hi all. I've been playing with some backdoors, spyware and trojans that are encrypted by packers and and undetected by most antiviruses. With all the firewall leaktesting, would you consider the firewall as the last line of defense? Or, maybe HIPS with a firewall background like DSA would be last in line because some malware piggybacks on trusted applications to find their way to the internet. Of all the products discussed in these forums, which one(s) would you consider the last line of defense? For me, it would be a good HIPS.
